Özet: The presence of thymol derivatives in the leaves and twigs of E. fortunei collected in Northern Vietnam was investigated. Five thymol derivatives, including new 9-O-angeloxy-10-hydroxy-8-methoxythymol, 10-acetoxy-9-chloro-8,9-dehydrothymol, 9-acetoxy-8,10-epoxythymol-3-O-isobutyrate, 8,10-epoxy-9-hydroxy-thymol-3-O-tiglate, and 9-acetoxy-8,10-epoxythymol-3-O-angelate together with six other compounds, including taraxasteryl acetate, o-coumaric acid, trans-melilotoside, (–)-loliolide, coumarin, and b-sitosterol were isolated. The structures of the isolated compounds were determined on the basis of MS and NMR spectroscopic data.
